Answer:

a) $530

b) $ 130

c) 20 months.

Step-by-step explanation:

a)

Total installment price:

As we have to pay a installment of $20 per month for 24 months; also there is a down payment of $ 50

Hence, the total installment paid=$ 50+20×24=$ (50+480)=$ 530

Hence the total installment price is $ 530.

b)

carrying charges:

Carrying charges are the charges one has to pay when installment price is subtracted from the cash price.

Carrying charge= $ 530-$ 400=$ 130

Hence, Carrying charges is $ 130.

c)

number of months needed to save the money at the monthly rate to buy the item for its cash price:

As the cash price is $ 400.

Let 'n' denote the number of months we have to save money at the monthly rate.

As the monthly rate is $20.

Hence 20 n= 400

⇒   n= (400/20)=20

Hence, for 20 months the money have to be saved to buy the item for it's cash price.

Mrs.Click has a strawberry patch in her garden. It's border is 4/5 meters wide and 3/2 meters long. What is the area of Mrs.Clic
pashok25 [27]

Answer

Mrs. Click's Garden is 6/5 or 1 1/5 square meters.

Explanation

Mrs. Click's has a rectangular garden. To find the area of a rectangle, you multiply the width by the length. To find the area of Mrs. Click's Garden, you multiply 4/5 by 3/2.

To multiply fractions, you multiply the numerator by the denominator.

4×3 is 12 and 5×2 is 10. You get the fraction 12/10, which can be simplified to 6/5, or 1 1/5.
